Buy-a-box promos are cards given away for purchasing a booster box at certain local stores. They are foil cards with alternate art, and some of them bear the five mana symbols arranged in a circle, a faction symbol, a clan symbol, a guild symbol or a set symbol as a watermark.

In North America, it was designed that the first 20 people buying a full box from a participating retailer would receive one of these promo's, however in Europe, the following rules applied to obtain one:

For M10 and Zendikar

* Obtain a stamp card from the retailer
* Receive one stamp for every booster you buy.
* Receive five stamps for every Intro Pack you buy.
* Get three BONUS stamps just for playing in Open Dueling at prereleases and launch parties!

Once you have collected 36 stamps, receive a unique promo card in your store

For Worldwake, buy 36 boosters or 5 Intro Packs or 24 boosters and 2 Intro Packs in one of the participating stores in Europe, you can get the special promo card Celestial Colonnade from this store (if stock is available)

What's Buy-a-Box?

The Buy-a-Box promotion encourages in-store sales of booster boxes.

Core-level-and-above WPN members who sign up in Wizards Event Reporter will receive a number of promo cards based on store level.

For each customer who purchases a full display of booster packs, you provide a Buy-a-Box promo card, while supplies last. (Online orders are not eligible and distribution is one card per person.)

To help customers participate in this promotion, your store will be listed in the Wizards Store and Event Locator as a Buy-a-Box promotion location.

Amonkhet will be the last season where Core-level and above WPN members must sign up in Wizards Event Reporter to participate in the Buy-a-Box program.

Even if you have already reviewed and agreed to the new WPN Terms and Conditions, you still need to schedule Buy-a-Box: Amonkhet to receive your kit. Beginning with Hour of Devastation, you will be automatically enrolled.
